GEORGE A. THOMPSON, OF OLIO, ARKANSAS, ASSIGNOR OF ONE-HALF TOWILLIAM 1. JAMES,

OF OLIO, ARKANSAS.

Application filed July 1, 1907.

T 0 all whom it may concern:

Be it known that I, GEORGE A. TnoMPsoN, citizen of the United States,residing at Olio, in the county of Scott and State of Arkansas, haveinvented certain new and useful Improvements in Ohurns, of which thefollowing is a specification.

The present invention relates to certain new and useful improvements inchurns of that ty e which embody a vertical reciproeating c asher, andaims to provide a novel construction whereby the oily globules may bequickly and thoroughly separated from the milk or cream.

The invention resides principally in the provision of a'novel mechanismfor operating the dasher rod, and in the means employed for clamping thechurn body in cooperative relation to the dasher operating mechanism.

For a full understanding of the invention and the merits thereof andalso to acquire a knowledge of the details of construction and of themeans for effecting the result, reference is to be had to the followingdescription and accompanying drawings, in which:

Figure 1 is a front elevation of a churn embodying the invention; Fig. 2is avertical sectional view on the line 22 of Fig. 1 Fig. 3 is anenlarged detail view of the clamp for locking the churn body inposition; and, Fig. 4 is a horizontal sectional view on the line 44 ofFig. 1.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The numeral 1 designates the base of the churn, and extending upwardlyfrom opposite sides of the base are the standards 2. A cross bar 3connects the intermediate portions of the standards 2, the said crossbar being formed at its end portions with openings receiving thestandards, and blocks 4 being applied to opposite sides of the standardsbetween the base and the cross bar. Bearing blocks 5 are mounted uponthe upper ends of the standards 2 and receive a shaft 6 formed with anintermediate crank portion 7. Fly wheels 8 and 9 are keyedupon orotherwise made rigid with opposite ends of the shaft 6, the fly wheel 9being shown as somewhat smaller than the fly wheel 8. The shaft 6 isalso provided with a pulley 10 which, in the present instance is locatedadjacent the Sp ecificationioffiLetters Patent.

gaging a drive wheel 12 mounted upon one of the standards 2. This flywheel 12 is provided with any suitable handle 13 by means of which thewheel may be turned and motion imparted to the shaft 6.

Swinging guide blocks 14 are mounted between the inner ends of thebearing blocks 5 and the intermediate cross bar 3 and are formed upontheir adjacent faces with the longitudinal grooves 15 receivingcorresponding tongues upon the vertical reciprocating cross head 16, thesaid guide blocks swing about a longitudinal axis. The upper end of thecross head is bifurcated and receives the lower extremity of a pitman17, the upper end of which is pivotally connected to the crank portion 7of the shaft 6 whereby when the said shaft is rotated, the cross head isgiven an up and down movement. A rod 18 projects downwardly from thecross head 16 and passes loosely through the cross bar 3, the lower endof the rod 18 having a socket formed therein designed to receive theupper end of the dasher rod 19, a set screw 20 being employed to producea rigid connection between the two members. The churn body 21 isdesigned to rest upon the base 1 between the standards 2 and is providedwith a cover 22 through which the dasher rod 19 slides freely. In orderto lock the churn body 21 in position, a pair of bails 23 are employed,the said bails comprising inverted U-shaped members, the arms of whichhave their lower extremities extended outwardly and pivotally connectedto the base. After the churn body 21 has been placed in position, thebails 23 are swung upwardly so as to engage the same and are held inthis position by means of the locking members 24. In the presentinstance, these locking members 24 are in the nature of hooks, the crossbar of each of the bails 23 having one of the hooks pivotally connectedthereto. After the churn has thus been locked in position, the dasher isgiven a quick reciprocating movement by turning the drive wheel 12 andthe milk or cream is thoroughly agitated in such a manner as to hastenthe formation of butter.

Having thus described the invention, what is claimed as new is:

1. In a churn, the combination of a base, a churn body resting removablyupon the base, a pair of inverted U -shaped swinging bails pivotallyconnected to the base and adapted to smaller fly wheel 9 and receives abelt 11 en- 1 be swung over the churn body from opposite sides thereof,hook members carried by the bails and serving to detachably connect thesame for the purpose of holding the churn body upon the base, and adasher operating mechanism mounted upon the base in 006perative relationto the churn body.

2. In a churn, the combination of a base, a standard upon the base, apair of oppositely disposed guide blocks carried by the standard andpivotally mounted so as to swing about a longitudinal axis, areciprocating cross head slidingly mounted between the oppositelydisposed swinging guide blocks, means for actuating the cross head, achurn body upon the base, a dasher within the churn body, and connectingmeans between the dasher and cross head.

3. In a churn, the combination of a base, a pair of standards carried bythe base, a cross ar connecting the standards, a bearing block mountedupon each of the standards, a shaft journaled in the bearing blocks andprovided with a crank portion, means for driving the shaft, a pair ofoppositely disposed guide-blocks mounted between the cross bar andbearing blocks so as to swing about a longitudinal axis, a reciprocatingcross head mounted between the guideblooks, connecting means between thecross head and the crank portion of the beforementioned shaft, a churnbody upon the base, a dasher within the churn body and connecting meansbetween the dasher and cross head.

In testimony whereof I aflix my signature in presence of two witnesses.

GEORGE A. THOMPSON.
